UK Study Finds New Car Models Emitting More CO2 Than Older Ones

A new research that suggested that the auto industry is taking backward steps in addressing the issue of climate change, claimed that more carbon dioxide is being produced by new cars that are sold in the United Kingdom compared to the older models.

To combat air pollution, cleaner internal combustion engine technology is used in cars that manage to reach the latest standards of emissions. But according to the consumer group Which? That was behind the research, there has been a rise in the average emissions of the greenhouse gas because of the relentless rise in demand for bigger and heavier models.

The study that included tests on 292 models released in the UK since 2017, found that 7 per cent more emissions were produced by the latest generation of cars compared to those that had been manufactured according to the earlier standards. According to government figures, about 18 per cent of the total emissions in the UK is accounted for by cars. Therefore, regulators and policy makers say that it is crucial to reduce emission from this sector for the country as a whole ot achieve the target or being a net zero carbon emitting country by 2050.

“It is shocking to see our tests uncover increasing levels of carbon dioxide emissions for the latest cars that are being built and sold to UK consumers. “Manufacturers must ensure that they are doing everything in their power to create cleaner vehicles that are fitter for our planet and its future,” said Lisa Barber, editor of Which? Magazine.

The research found that on the overall, 162.1g of CO2 per kilometer was produced by cars that met the latest emissions regulations (standards known as Euro 6d and Euro 6d-temp) that was 10.5g more than those produced by the cars of the previous generation (Euro 6b and Euro 6c).

The emission levels of the new generation of cars was far higher than the 95g target that has to be mandatorily met by carmakers across all EU sales for them to avoid fines. And in order to meet the rules, the focus of car makers all across Europe is on manufacturing of and selling of new electric models. There are also a number of companies that are also targeting to meet the regulatory standards by increasing sale of hybrid models that work with a combination of battery supplied power and an internal combustion engine for running.

“We can’t comment on the results of non-official tests by commercial organisations where the methodology is unclear. Only the official, Europe-wide WLTP [Worldwide Harmonised Light Vehicle Test Procedure] test – the toughest and most comprehensive in the world – can be relied upon by consumers to accurately compare vehicles on a like-for-like and repeatable basis. This shows that new cars emit, on average, some 29.3% less CO2 than models produced in 2000, the effect of which drivers can see at the pump,” said Mike Hawes, chief executive of the Society of Motor Manufacturers and Traders (SMMT), the industry lobby group.
